The -ipresent invention `relates 'to fthecleaning and humidifying ofthe suctionrairfor 'aniint'ernah combustion engine.

Itiszanobject of the invention .to provide an apparatus that will thoroughly clean: the air prior to delivery to the carburetor of the 'internal combustion 'engine and that will increase substantially the waterv content of the air which, as is well known, increases the eiciency of 'the internal combustion engine.

A still further object of the invention is to provide a construction wherein due to the enlarged sur-face contacted by the air an increased cleaning and humidifying'action is secured without increasing the overall dimensions oi the devloer.

.A stilly further object of the invention is `to provide a compact structure which may bel quickly and.v easily disassembled: for cleaning, replacement and repair purposes.

With-the above .and other objects in View which wllappear from the detailed descriptionV below, the invention isshown inf the drawings in which:

'Whena humidifier is usedfwithI an internal combustion v.engine the engine .efficiency improves during operation if the water content of the .air auctioned. into the engine during the suction stroke thereof is increased. The humidiiier and cleaner of the present invention increases the Water content of the air approximately 300% above the yield. of humidii'iers at present in use by enlarging the available surface of the porous material over which the air passes prior to be ing suctioned into the engine.

Referring to the'drawings, wherein likereference. characters indicate likeparts, one modifica tion of; the Ainvention is showninFigs. 1v and 2 whereinV the humidifying and cleaningelement Hi is constructed of ceramic porous material or any.- other porous hygroscopic material, such as powderedmetal, etc.

The elementv I .is shaped as shown in Figs. l and 2 w-ith a plurality of fins Il and at the base thereof with a cylindrical hollow portionIZ con stituting thewaterreservoir:

Water is fed into the reservoir I2 through the conduit. :i3 "formed in: anipple I4 cast integrally with 'theelement' id. Attached to the nipple I4 isfa flexible connection I5 'preferably of rubber, whichis attached'iat Ytl'leother end to a metal connection I 'E which in turn is connected preferably by a flexible connection with the cooling system for the internal combustion engine so that water. is' constantly maintained in the water reservoir 12.

vThe'.:ele'mentv I0 rests upon a feltlor rubber ring H which in turn rests upon the annular metal base I8. The inner periphery I9 of the base`v Isis vturned downwardly 'and to this is secured; preferably by spot welding, a clamp and clarnpg-bolty assembly" 2Br which isprovided for connecting the cleaner and lhu'midiier lassembly with a conduit. leading to the intake side of the carburetor.

' Th'e base V'I may be'provided with grooves such asV ZI' for vstrengthening purposes. The outer periphery of the base I8 is also turned down-v wardly'as shown at 23'and to this is secured in anydesiredwa'y preferably by spot welding the annular oil container 23. The oil container 23 at its upperinterior 'side is provided with a flange 2li to prevent splashing of the oil 2'5 in the container; At "the .interior side Yo1 the outer side of thecontainer 23 there is' provided a supporting elbow 26" whichfmaybe spot welded to the wall of the container 23.

Resting upon the supporting elbow 2S is the air filter 27. The 'air filter is formed as a ring shaped 'container with' an interior imperforate metallicwall Zwhich'is secured by a flange 29 at i the upper portion thereof to the exterior peripheral' wall-'Stof theair filter. The exterior wall 30 is provided with: perforations 3| and at the bottom-is curvedy to form the bottom vwall 3E of the air lter which is also perforated as shown-:at 33.. The bettomwall-SQ of the filter is providedr-with.. an upwardly extending flange iililwhichis secured tothe lower portion-of the interier'wal'lfZB as show-n. With the construction .described the air .enters through the. .perforations tI,- passesy througlfrY the lter-:forming: vmaterial 35.-such-i-as--,capperi-filings, glass wooLor the like andv then: leaves. the airv filter.: 2i through the openings 3sat the :bottom thereof. Upon .leaving thefair filterfZI. through-the openings 33 .the air coince-in: contactzwithf the upper surface of the oil. 25 where it isfurther cleansed.

Positioneduponthe topr of the-humidfying element ,i EL isf-.a rubber washer..36/.andsupported thereon is a metallic ring-shapedrelement. 31 oi metalaw-hich acts as afsi-lencer. ThesilencerI is fprovidedat-'tsrupper portion witha circular seat 38 upon which rests a spider 39. A cover 40 preferably constructed of aluminum is positioned above the spider 39 and frictionally engages at its lower edge 4I with the top portion ofthe air filter 21. Extending through the central portion of the cover 40 and the spider 39 is a clamping rod 42 having a hook p43 at the lower end thereof which engages the bail 44 whose ends 45 engage in openings provided in the upper portion of the clamp and clamp-bolt assembly 20. A nut 46 is secured to the clamping rod 42 supporting the yoke 39 and nuts 41 also on the rod 42 space the cover 40 from the yoke 39. A wing nut 48 threaded upon the rod 42 secures the entire assembly together.

When the cleansed air leaves the surface of the oil 25 it passes upwardly and contacts the exterior surface of the ns I I. Due to the moisture upon such fins a further cleansing action takes place with respect to the air and such cleansing action isl continued as the air reverses its direction at the top of the element I and passes downwardly through the Venturi shaped opening 49 provided in the element I0 on its Way to the carburetor.

During the passage of the air rst across the exterior wall of the element I 0 and then through the interior conduit 49 the air entrains from the enlarged iin construction an increased quantity of water. It has been found in actual practice that substantially 300% increase is secured in the water content of the air by the construction described above that in usual humidifiers and also due to the enlarged surface an improved cleansing action is also obtained.

If desired the water reservoir I2 may be connected in circuit with the water system of the engine but it has been found that generally this is not necessary and one connection as shown is suii'icient.

The pipe I 9 is supported in the cover 40 by means of an eyelet 50 of any desired material.

It is believed that the operation of the humidier and cleanser is evident from the above description and also that in order to replace or cleanse any portions thereof it is only necessary to remove the wing nut 48 and lift up the cover 40. The entire assembly is then easy of access.

The form of the invention shown in Fig. 3 and 4 will now be described.

In this modification the oil bath assisting in the cleansing of the air is eliminated. The humidifying and cleansing element I0 is similar in construction to that above described and the same applies to the various elements having the same reference characters.

However, the base 58 supporting the structure is of ring shape and extends suiiciently to support the air filtering element 59 in addition to the washer 60 upon which the element I0 is supported. The filtering element 59 is formed by two concentric plates 6I and 62. The plate 6I is provided with perforations 63 and the interior plate 62 is provided with perforations 64 while between the two plates 6I and'62 there is placed the filter material such as copper lings, glass wool or the like, 65. The cover 6B in this modication is provided at the interior with an angle plate 61 whose upwardly extending leg is secured to the cover 66 in any desired way such as by rivets 63. The horizontal leg 69 extending towards the interior closes the upper end of the filtering element 59.

y Connected to the nipple I4 is a exible conduit 'I0 which is connected in turn to the verti- CTI cally disposed connection 'I3 passing through an opening 'II provided in the base 58 wherein is disposed a bushing '!2. The connection 'I3 is connected by any desired means to the water system of the internal combustion engine.

The inner plate 62 of the air lter is provided with a recessed portion T4, shown in Fig. 4, for accommodating the connection 'I3 and the conduit 10.

Also the base plate 58 is provided with struck up resilient tongues 'I5 for accurately centering the element I0 upon the base member 58.

The operation of the modification described above is similar to that of the rst modification described except that the air as it enters from outside the air lter 59 through the openings E3 passes directly therethrough and escapes through the openings 84 and then contacts the ns II before reversing its direction and passing through the Venturi central opening of the element I0.

In this case also by removing the Wing nut 48 the cover 69 may be removed and this allows all of the interior elements to be replaced or cleaned easily.
